Pip install fails on OS X Mojave

[sarahdavis23]

I've been trying to install version 0.2.1 on Mojave but it's somehow unhappy with gcc. I installed anaconda and I've tried both in the base environment and created another virtual environment. The error message is below. I get a similar message if I don't specify a version.

I've done the things suggested in this link but it doesn't seem to help: https://stackoverflow.com/questions/52509602/cant-compile-c-program-on-a-mac-after-upgrade-to-mojave

Maybe this is relevant: hkwi/python-geohash#27

did u solve it?

[ShiqinHuo]

Try conda install

[sarahdavis23]

conda install doesn't work either.
It's actually a problem with python-sasl. It needs to use a newer version of the C compiler. @rboyatt has made a fix for that which means I can install this package but I still couldn't get thrift_sasl to work, at which point I gave up.

[rboyatt]

The problem seems to be in python-sasl. On recent versions of OS X you need to ensure libc++ is being used as the C++ library by specifying it with extra_compile_args. This allows python-sasl to compile and resolves the problem being described above.

Here's a fork of python-sasl with the necessary changes - https://github.com/rboyatt/python-sasl/tree/stdlib-osx

MacOS:

brew install gcc@4.9
env CC=/usr/local/bin/gcc-4.9 pip install thrift_sasl==0.2.1

[JoshRosen]

I found a simple workaround: modify the build to target OS X 10.9, which has the side effect of ensuring that libc++ is used: cloudera/python-sasl#13. I originally tried using @rboyatt's suggestion of passing the -stdlib=libc++ extra compiler flag, but that still failed for me with the same error.

[zscore]

For anybody who wants to use @JoshRosen's fix, you can install it via pip with the following command:
pip install git+https://github.com/JoshRosen/python-sasl.git@fix-build-with-newer-xcode

[claudiokc]

This worked for me!

[azhar22k]

This worked for me

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

[nmorenol]

Try conda install

It work for me. Thanks.
